Description
1. We started this course while there were short, cold days in winter. Now it is warm (sometimes) and light. Why is that the case?
2. If we find a planet like Earth, but is twice as massive and twice the size, how would the force of gravity on its surface compare to Earth’s? (I’m looking for a numerical answer)
3. Why have simple impact craters been visited by every Apollo mission as well as by all the Mars rovers? (Hint: it is not only because they are common!)
4. Larger worlds are geologically active for a longer time than smaller worlds since larger worlds...
(a) have more radioactive elements and lose heat faster
(b) have more radioactive elements and lose heat slower
(c) have fewer radioactive elements and lose heat faster
(d) have fewer radioactive elements and lose heat slower
